A bull sea lion shows a brand burned into its hide by the Oregon Department of Fish and Wildlife, to monitor it from season to season as it travels between California, Oregon and Washington. Some California sea lions, such as this one C-704, prey upon migrating salmon that gather in the downstream waters and fish ladders of Bonneville Dam on the Columbia River. The "C" in its brand denotes Columbia River. These sea lions also form bachelor colonies that haul out on public docks in Astoria's East Mooring Basin and elsewhere, where they can damage or even sink docks. Pinniped Research Picture.
